Genes affected

ANKRD17 (HGNC:23575): (ankyrin repeat domain 17) The protein encoded by this gene belongs to the family of ankyrin repeat-containing proteins, and contains two distinct arrays of ankyrin repeats in its amino-terminal region, one with 15 ankyrin repeats, and the other with 10 ankyrin repeats. It also contains a nuclear export signal, nuclear localization signal, and a cyclin-binding RXL motif. Localization of this protein to the nucleus has been shown experimentally, and interactions between this protein and cyclin-dependent kinase 2 have been observed. It has been suggested that this protein plays a role in both DNA replication and in both anti-viral and anti-bacterial innate immune pathways. Alternative splicing results in multiple transcript variants encoding different isoforms. [provided by RefSeq, Dec 2015]

ACMG classification

Verdict is Uncertain_significance. Variant got 2 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• PP2: Missense variant in gene, where missense usually causes diseases (based on misZ statistic), ANKRD17. . Gene score misZ 5.3588 (greater than the threshold 3.09). Trascript score misZ 6.9945 (greater than threshold 3.09). GenCC has associacion of gene with syndromic intellectual disability, Chopra-Amiel-Gordon syndrome.
• BP4: Computational evidence support a benign effect (MetaRNN=0.33569223).
